Water Heater Replacement in Westminster, CO
Water Heater Replacement in Westminster, CO
A failing water heater rarely fixes itself. If your tank is past the decade mark, producing rusty water, or leaving you with cold showers halfway through your morning routine, you need a lasting solution, not another expensive band-aid repair.
Big Apple Plumbing provides complete, code-compliant water heater replacements for homeowners across Westminster. Whether you need a standard gas tank swap or a high-efficiency tankless upgrade, our licensed team ensures your home’s hot water supply is restored with upfront pricing and zero hidden fees.
Westminster’s Water Hardness and Your Tank's Lifespan
Westminster’s municipal water supply is generally considered moderately hard, averaging around 6.9 grains per gallon (GPG). While this is safe for drinking, it acts as a slow-motion wrecking ball for standard water heaters.
As water heats up, the calcium and magnesium in the water crystallize and settle at the bottom of your tank. For homes in Westminster, this causes two critical failures:
Overheated Gas Tanks: In a gas water heater, this sediment barrier sits directly above the burner. The tank has to heat the rock-hard sediment before it can heat your water. This severely overheats the bottom of the tank, cracking the glass lining and causing the steel to rust through and leak.
Burned-Out Electric Elements: In electric tanks, the sediment literally buries the lower heating element, causing it to overwork, short out, and eventually fail.
If you hear popping, rumbling, or crackling noises coming from your water heater, that is boiling water trapped under Westminster hard-water sediment. Once the tank begins leaking from the base, replacement is the only safe option.
Cold showers because your water heater finally gave out? A full replacement gets your hot water back for good, not just until the next breakdown. Schedule your replacement and stop patching a unit that's done.
Meeting City of Westminster Code Requirements
Plumbing codes change, and replacing a water heater today requires stricter safety measures than it did 10 or 15 years ago. As a licensed contractor, Big Apple Plumbing handles all local compliance.
When replacing a unit in Westminster, the city requires specific documentation and upgrades depending on the system:
Permitting & Inspections: We handle the residential permits required by the city for all water heater installations.
Standard Tanks: The city requires proper sizing (BTU and gallon capacity) to ensure safe operation and proper venting. We ensure your new atmospheric or power-vented tank is properly drafted.
Tankless Conversions: Upgrading to a tankless system in Westminster requires a submitted gas pipe plan to ensure your home’s gas lines can handle the increased on-demand BTU load. We handle the load calculations and gas line retrofits so your system is safe and approved.
Colorado Emissions: We ensure all new gas units installed meet Colorado’s upcoming ultra-low NOx emissions standards.
Upgrading Your Hot Water: Tank vs. Tankless
Whether you live in a townhome near the Westminster Station RTD B-Line or a larger single-family home backing up to Standley Lake, we size your replacement based on your household’s actual demand.
Standard Tank Replacements
The fastest and most cost-effective solution if your home is already set up for a tank. We remove your old, sediment-heavy unit and install a high-efficiency 40- or 50-gallon gas or electric model. We include all necessary code upgrades, like a thermal expansion tank and a hard-piped safety drain pan.
Tankless Water Heater Upgrades
If you have a growing family tired of running out of hot water, or you just want to reclaim floor space in your utility room, tankless is the way to go. These units heat water instantly as it passes through the heat exchanger, bypassing the sediment buildup that plagues traditional tanks. While it requires an upfront investment to modify your gas and venting lines, the endless hot water and long-term energy savings make it a highly popular choice for Westminster homeowners.

Schedule serviceFrequently Asked Questions
How long does a full water heater replacement take? Most standard tank replacements take 2 to 4 hours. Tankless conversions or jobs needing gas line or electrical upgrades can take longer.
Can you replace my water heater the same day I call? Often yes, for standard tank replacements, if the unit is in stock and no major electrical or gas work is needed.
Do I have to replace my working water heater because of the new Colorado law? No. Colorado’s HB23-1161 emissions rule applies to new units sold or installed starting January 1, 2026. It doesn’t require you to replace a water heater that’s still working.
Should I repair or replace? If your unit is under 6 years old and the problem is a single part, repair usually makes sense. Past 10 years, or with more than one symptom on the list above, replacement is typically the better value.
What warranty comes with a new installation? Labor is covered by our 1-year warranty. Manufacturer warranty on the unit itself varies by brand and model, we’ll go over that when we quote the job.

Whatever type of water heater you have now, we can replace it with the same setup or something better suited to your household. Gas tank, electric tank, and tankless units all come with different venting, sizing, and code requirements, and we handle all three.
If you’re on gas and considering a switch to electric or tankless during your replacement, ask us about it. Sometimes it’s a straightforward swap, sometimes it involves more electrical or venting work than it’s worth. We’ll tell you which applies to your home before you commit to anything.
